1. What Dorzolamide and Timolol EG is and what it is used for

Dorzolamide and Timololo EG is a combination of two active substances: dorzolamide and timolol.

  • Dorzolamide belongs to a group of medicines called "carbonic anhydrase inhibitors".
  • Timolol belongs to a group of medicines called "beta-blockers".

Dorzolamide and Timololo EG is prescribed to reduce intraocular pressure in the treatment of glaucoma when beta-blocker eye drops used alone are not sufficient.

2. What you need to know before using Dorzolamide and Timololo EG

Do not use Dorzolamide and Timololo EG eye drops, solution

  • if you are allergic to dorzolamide or timolol, to beta-blockers, or to any of the other ingredients of this medicine (listed in section 6);
  • if you have or have previously had respiratory problems such as asthma, severe chronic obstructive bronchitis (a serious lung condition that may cause shortness of breath, difficulty breathing, and/or long-lasting cough);
  • if you have severe kidney problems or a history of kidney stones;
  • if you have a blood pH disorder (acid-base imbalance);
  • if you have certain heart conditions, including some heart rhythm disorders causing abnormally slow heart rate, or severe heart failure.

If you think any of these conditions apply to you, use Dorzolamide and Timololo EG only after consulting your doctor.
Warnings and precautions
Talk to your doctor or pharmacist before using Dorzolamide and Timololo EG, especially if you currently have or have previously had

  • coronary heart disease (symptoms may include chest pain [even at rest] or tightness, shortness of breath, or suffocation), heart failure, low blood pressure;
  • breathing problems, asthma, or chronic obstructive pulmonary disease;
  • poor blood circulation (such as Raynaud's disease or syndrome);
  • diabetes, as timolol may mask the signs and symptoms of hypoglycaemia;
  • overactive thyroid gland, as timolol may mask its signs and symptoms;
  • any allergies to medicines you have taken.

Before undergoing surgery, inform your doctor that you are using Dorzolamide and Timololo EG, as dorzolamide/timololo may alter the effect of certain medicines used during anaesthesia. A sudden drop in blood pressure associated with the anaesthetic may occur.
Inform your doctor if you have or have had liver problems, if you suffer from muscle weakness, or if you have been diagnosed with myasthenia gravis.
If conjunctivitis (redness and irritation of the eyes), swelling of the eye or eyelids, or skin rash or itching inside or around the eye occurs, contact your doctor immediately. These symptoms may be caused by an allergic reaction or may be an adverse effect of Dorzolamide and Timololo EG (see section 4 "Possible side effects").
If you think this medicine is causing you an allergic reaction or hypersensitivity (for example, skin rash, serious skin reactions, or redness and itching of the eye), stop using it and contact your doctor immediately.
Inform your doctor if you develop an eye infection, suffer an eye injury, have undergone eye surgery, develop other reactions, or if your symptoms worsen.
If you wear soft contact lenses, it is important that you remove the lenses before using the eye drops and wait at least 15 minutes after instillation before reinserting them into the eye. This is because the preservative benzalkonium chloride contained in the product may discolour them.
Children
Experience with Dorzolamide and Timololo EG in neonates and children is limited.
Elderly
In clinical studies with dorzolamide/timololo eye drops, solution, the effects of dorzolamide/timololo eye drops, solution were similar in both elderly and younger patients.
If you engage in sports: using this medicine without therapeutic need constitutes doping and may lead to a positive result in anti-doping tests.
Other medicines and Dorzolamide and Timololo EG
Dorzolamide and Timololo EG may affect or be affected by other medicines you are using, including other eye drops for the treatment of glaucoma. Inform your doctor if you are using or intend to use medicines to lower blood pressure, medicines for the heart, or medicines for the treatment of diabetes.
Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. This is especially important:

  • if you are taking antihypertensive medicines used to lower high blood pressure or medicines for heart conditions such as calcium channel blockers and beta-blockers, or digoxin;
  • if you are taking medicines for the treatment of heart rhythm disorders or irregularities such as quinidine (used to treat certain types of malaria) or digoxin;
  • if you are using another eye drop containing a beta-blocker;
  • if you are taking another carbonic anhydrase inhibitor, for example acetazolamide. This type of medicine may be taken orally, as eye drops, or by other routes;
  • if you are taking monoamine oxidase inhibitors (MAO inhibitors) or selective serotonin reuptake inhibitors (SSRIs, e.g. fluoxetine and paroxetine), both used to treat depression or other conditions;
  • if you are taking a parasympathomimetic medicine, which may have been prescribed to help you urinate. Parasympathomimetics are a particular type of medicine sometimes used to restore normal intestinal movements;
  • if you are taking narcotic medicines such as morphine, used to treat moderate to severe pain, or if you are taking high doses of acetylsalicylic acid. Although there is no evidence of interaction between dorzolamide hydrochloride and acetylsalicylic acid, some other medicines related to dorzolamide hydrochloride taken orally are known to interact with acetylsalicylic acid;
  • if you are taking medicines for the treatment of diabetes or hyperglycaemia;
  • if you are taking epinephrine (adrenaline).

3. How to use Dorzolamide and Timololo EG

Use this medicine exactly as directed by your doctor. If you have any doubts, consult your doctor or pharmacist.
Your doctor will determine the appropriate dosage and duration of treatment.

Adults

If you are using Dorzolamide and Timololo EG together with another eye drop, wait at least 10 minutes between the administration of Dorzolamide and Timololo EG and the other medicine.

Do not change the dosage without first consulting your doctor. If you need to stop treatment, contact your doctor immediately.

Avoid letting the tip of the bottle touch the eye or surrounding area. Contamination with bacteria may occur, which could lead to eye infections and potentially result in damage to the eye, including loss of vision. To prevent any kind of contamination, ensure that the tip of the container does not come into contact with any surface.

To ensure correct dosing, the dropper tip must not be widened.
